Meadowfoam seed oil is a light, slightly greasy feeling oil that has a long shelf life and can boost the shelf life of other oils. I thought it would be nice to combine it in a lotion with Ritamulse SCG as the emulsifier because that offers a slightly thickened and dry feeling, with a little cetyl alcohol to offer thickening, slip, and glide.
In the water phase, I used distilled water with 3% glycerin as my humectant and 0.5% allantoin to work as my barrier ingredient. (I would normally use a combination of cocoa butter, allantoin, and dimethicone as my three approved barrier ingredients, but I only had six ingredients to work with, and dimethicone was one too many!)
If you're the type who thinks about things being natural, I would say you could call this lotion 95.5% natural as Ritamulse SCG is Ecocert. The 4.5% I don't consider natural would be my fragrance oil, preservative, and cetyl alcohol.
SIX INGREDIENT LOTION WITH MEADOWFOAM SEED OIL & COCOA BUTTER
HEATED WATER PHASE
HEATED OIL PHASE
5% cocoa butter
16% meadowfoam seed oil
3% cetyl alcohol
8% Ritamulse SCG
COOL DOWN PHASE
0.5% preservative (liquid Germall Plus)
1% fragrance oil
A double batch of this made 6 ounces or 180 ml of lotion for me.
What do I think of it? As a body lotion, it's a bit thin for my tastes. I found it to be quite watery as I put it on, and it didn't stay greasy long enough for me to rub it in as well as I would have liked. After two hours, it didn't feel like I had really applied any lotion to my skin, and the next morning, it definitely wasn't there.
If I wanted to thicken it as a body lotion, I'd go to 10% cocoa butter or another butter to make it thicker or I'd use a thicker feeling oil like rice bran or olive oil with the meadowfoam seed oil. I wouldn't change anything as a hand lotion!
Remember that using different ingredients than I've used here will change the skin feel. If you use e-wax or Polawax, this will be a greasier feeling lotion, so consider using mango butter in place of some of the cocoa butter so it'll stay less greasy feeling. BTMS-50 or Rita BTMS-225 will make it feel slightly drier than my version. Feel free to use cetearyl alcohol in place of the cetyl alcohol for a waxier feeling lotion, and feel free to replace the meadowfoam seed oil for any other oil or ester you like. Feel free to try other liquids in place of the water, such as aloe vera or a flowery hydrosol.
Have fun formulating!
